1.A Dewar Flask, also known as a dewar bottle, is an insulated container used for storing and transporting cryogenic liquid gases. It consists of two layers of metal shells, with a vacuum in the middle and filled with insulating materials to reduce heat conduction. The design of Dewar flasks enables them to maintain an internal low-temperature environment, thereby effectively storing liquid gases. The following are the main advantages of Dewar flask packaging:
High safety: Dewar flasks are equipped with multi-level safety protection devices, are easy and reliable to operate, and have good safety.
Large storage capacity: Dewar flasks have a large storage capacity, which can reduce storage space, decrease bottle changing operations, and improve work efficiency.
High gas utilization rate: As the liquid gas is directly vaporized for supply, it avoids the possible secondary pollution of the gas in the cylinder from filling, transportation to use, so the purity of the supplied gas is relatively high.
Self-pressurization control: The Dewar flask is equipped with a self-pressurization control function, and the energy-saving route is built-in with a vaporizer, pressure and liquid level indication device.
2.The packaging and transportation advantages of container racks mainly include the following points:
Compact structure: The gas container compartment adopts a metal structure frame, featuring a compact structure, reasonable design, light weight and strong tensile strength.
Simple operation: The container compartment is a technologically advanced and high-tech filling and converging device. It is easy to operate and convenient to transport.
Improving work efficiency: The container rack is suitable for units and users with containerized gas supply and large-scale gas consumption, making it convenient for forklifts to load, cranes to lift, vehicles to transport, and for any movement of the work site.
High safety: The container compartment is convenient, safe and reliable to use, with high working efficiency. It is a timely emerging device in China at present, influenced by foreign countries.
